6 Claims. 1

This invention relates to. improvements in hair curling devices andmore. particularly to devices of the type disclosed. in my Patent No-2,421,008 of May 27, 1947,. which are intended for use in the cold. setor roller method of hair curling.

In. the usual cold set method of hair curling,v the, hair ends. becomeunset and loosely curled: sooner. than the main body of the. roll,thereby necessitating a resetting of the entire coifiure. Also, theconventional type of rollers may be: fixed only in positions along: thehair length a. half or full revolution apart, and. when held close tothe scalp, will draw the; hair so tightly as to cause extremediscomfort, while the next position. will leave a slight. uncurledlength. of hair.

While the device of my prior patent overcame.- these. difiiculties, it.relied solely' on the retractable U-shaped wire member for its. lockingfunction, while the finger member which clampsagainst the main portionof the curl was not. held ina fixed position and could workloose on thecurl-..

It is a primary object of this invention. to provide: a cold set haircurler which produces more, tightly coiled; hair ends than in theremaining; length, thereby increasing the effectiveness of thetreatment.

Another object. of. the invention is to provide: a. positive.- lockingarrangement in. a hair curler of the. cold set type, which effectivelyholds both the finger portion. and the wire clamp. of. such a. curleragainst movement.

A further object of the invention. is toprovide. a. positive lockingarrangement: which. permits fixing; sucha curler in adjustable andselectivepositions. along a strand of hair.

Other objects reside innovel details ofconstruction and novelcombinations and arrangementsof parts, all of which will be describedin. the: course of. the following description.

In the drawings, in which like parts have been designated similarly,

Fig.1 is-a perspective view of. a hair'curler ems bodying features. ofthe present invention; and showing the position of. the hair strand, bydotted line representation;

Fig. 2 is a side elevation: of the, curler shown. in Fig. 1 with theretracted. positions. of the. mechanism. and the hair strand. positionindicated. by. dotted line representation; and

Fig. 3 is a. developed. section taken along the line. 33,. Fig; 2..

Before. describing the details of the present invention, it. is to beunderstood that the inven- .tion. is. not limited. in its application tothe details. of construction and arrangement of parts.

illustrated in the accompanying drawing, since the invention is capableof other embodiments and of being practiced in various ways. It is to befurther understood that the. terminology employed herein is for purposesof description and not in limitation as it is not intended to limit theinvention. except as set forth in the appended claims.

The curler shown in the drawing preferably comprises a tubular bodyportion 4, the cross section of which progressively narrows from a pointadjacent its respective ends 5 and 6- to a central point, and has atintervals throughout its length a series of apertures l. A. recess 8 isprovided at end 6 to receive an extension on a finger member 8 whichisfolded back upon itself to-provide a pivotal attachment of the member onthe body as shown at Ill.

The finger member 9 has its greatest width adjoining pivot 19 andterminates at each side in at least one and preferably two rolledportions adapted to function as sockets I? for the reception of alocking wire l3, generally of U- shape and preferably having the outerends of its leg portions flattened as shown at M- (Fig. 2) to preventwithdrawal through the socket members l2 after once assembled.Preferably, finger Si conforms in contour to the external shape of body4 so that it will lie flat against said body throughout its length, anda series of apertures 15- are provided.- in finger 9.

The cross connecting portion of wire [3- extends laterally from thelegportions and then loops in U or V formation It so that the lateralportions ll function asa stop-to engage the end 6 of body 4 while theloop It acts as a pull for manipulation of the wire in the manner to besubsequently described. At least one or prefera bly two. shoulders i8(as shown) are. formed on the end- 6 0i the body portion to provide arest for pull [6 when wire I3 is in its normally re.- tractedposition.

In the use. of the devicehe-reinbefore described; wire. i3 is. drawnfrom its completely retracted:

position a distance sumcient to move pull 1.6 out;

of contact with shoulders l8; thuspermitting the Wire to be used inrotating finger 9 so as to move it from the full line position to thedotted line position shown in Fig. 2. Astrand of hair suita bly treatedwith Wave solution. or otherwise prepared for curling is wound aboutbody 4' and may be drawn as: tightly as desired, after which finger 9 ismoved to the reclining position overhanging body 4 and the wire I3 isthen moved into its retracted position with the pull [6 seated onshoulders l8 as illustrated in Fig. 2, in which position the rotation offinger 9 about pivot I is prevented by the aforesaid engagement of thepull with the shoulders. In this position, the leg portions of wire 13also hold the outer surface of the wound strand in position and it isallowed to remain until the curl is sufiiciently set to permit removalof the device. The provision of the holes T in body 4 and IS in finger 9insures suificient air circulation through the body and finger portionswhile the unit is holding the strand to permit rapid drying andevaporation of contained moisture.

Due to the clamping action of finger 9 when the wire is in its retractedposition, the tightly wound strand is prevented from slipping asfrequently occurs in the use of devices of this general character.Despite this positive gripping action, the manner of fastening thestrand in position insures against undue pulling or twisting which wouldbe a source of discomfort to the user.

Devices made in accordance with the structure shown and described may beformed of any suitable material, such as plastic, metal or the like. Ihave found that a die-cast aluminum construction is particularlydesirable because of the light weight of the assembled device and thelow cost of manufacture. Preferably, the wire l3 will be steel stock.

What I claim and desire to secure by Letters Patent is:

l. A device of the character described, comprising an elongated bodyhaving a shouldered surface at one of its ends, clamping means pivotallyattached to said body adjacent the shouldered end for rotation throughsubstantially ninety degrees and normally extending longitudinally ofsaid body in closely overhanging relation thereto so as to thereby holda coil of hair wound about the body against slippage, and a U-shapedmember having legs slidably mounted in socket-forming surfaces of theclamping means for pivotal movement therewith and extending into spacedsuperposed relation with the body so that the legs of said member willhold other convolutions wound about said coil and said clamping means,and said U-shaped member having a portion engaging the shoulderedsurface of the body to arrest the pivotal movement of said clampingmeans when the U-shaped member is in said superposed position.
